If DNA-human life survives and spreads outward into the wider universe, it will be subsequent to the shedding of superstition, the embracing of the moral equality of all humans, and the end of violence as a means of social organization. I have high hopes that this will be the case. Pessimism about the ability for humankind to evolve into a non-violent social organism is understandable, but short-sighted. The recognition of the value of human life in and of itself and the categorization of "others" outside the tribe as human is literally hundreds of years old on a planet where mammals have existed for hundreds of millions of years and humans for tens or hundreds of thousands. Human consciousness and self-awareness is increasing rapidly and the mechanistic superstitions pushing back against that growth are slowly falling away.
It is entirely possible that the project of a sane, rationally organized global society will take numerous generations and collapses in social complexity to come to fruition. The foundational ideas--reason, evidence, non-violence and it's corollary, freedom--are thoroughly and increasingly documented. In any context, they provide a striking contrast and unbeatable alternative to superstition, illusion, dominance and hierarchy. While the rear-guard action of reactionaries might last centuries, this is, viewed objectively, a very short period of time.
In the end, the ideas of reason, non-violence, and human equality are the most survivable and, at the rate they are growing, it won't be long before they are ascendant. I believe this ascendancy and the technological explosions that will follow will out pace entropy--at least in the short term and eventually who knows?
